Gears
Derailleur System
Some of Dyu E-Bike go with gears, which consists of:
• A rear sprocket cluster, called a freewheel or cog set
• A rear derailleur
• One swifter
• One control cable
• One front sprocket called a chaining
• A drive chain
There are many different types of swifter mechanisms, each preferred for specific
Applications because of its ergonomic, performance and price characteristics.
A downshift is a shift to a lower or lower gear, one which is easier to pedal. An upshift is a shift to a higher or faster gear, one which is harder to
pedal. For example, you can downshift to a lower gear to make pedaling easier on a hill.
On the other hand, you may upshift to a higher gear when you wish to go faster.
Whether up-shifting or downshifting, the derailleur system requires that the drive
Chain be moving forward and be under at least some tension. A derailleur will
Shift only if you are pedaling forward.
Caution:__________________________________________________
Never move the swifter while pedaling backward. Also do not pedal backwards after moving the swifter. Either of these actions could jam chain
and cause serious damage to the E-Bikes.
The derailleur system includes the front and rear derailleur, the shift levers,
and the derailleur control cables, all of which must function properly for smooth
gear
shifting to occur.
Derailleur
Although the front and rear derailleur are initially adjusted in our factory, you will
need to inspect and read just both before riding bicycle.
Rear Derailleur
Begin by shifting the rear swifter to largest number indicated, loosen the cable
from the rear derailleur cable anchor bolt, and place the chain on the smallest
sprocket.
Adjust the high limit screw so that the guide pulley and the smallest sprocket
are lined up vertically. Re-tighten the cable, pull out any slack, and re-tighten
the anchor bolt securely. Shifting through the gears, making sure that each gear
is achieved quietly and without hesitation. If necessary, use the barrel adjuster
to fine tune the cable tension by turning it the direction you want the chain to
go. For example, turning clockwise will loose the cable tension and move the
chain away from the wheel, while turning counter-clockwise will tighten cable
tension and direct the chain to the wheel.

PARAMETERS
Remark: Many factors will affect the max speed,such as power,load,tyre pressure,road conditions,chain,lubrication degree etc.
Mileage has been measured on basis of temperature 25℃,load of 60KG,speed of 15-20KM/H,smooth and hard road,and from
full battery to dead battery. It also is subjected to other factors,such as driving habits,temperature,load,tyre presure,road
conditions etc.”
